In Great Britain May 28, 1930 3 Claims. (Cl. 2220-65) This inventionrelates to. sanitary receptacles;

for dust and refuse and particularly to paper and/or fabric bags adaptedto be inserted in such receptacles to receive the dust and refuse 8' andsubsequently to be removed. from the recep-- tacles whilst closed upontheir contents, and the invention has for its object to provide improvedforms of bags for the purpose.

According to the present invention the im-, 10' proved bag which isadapted to be inserted as a lining in a domestic metal or other refusereceptacle or dustbin is formed, as a manua factured article ready forinsertion intothe dustbin, with a bottom adapted to rest upon the bottomof the dustbin or upon a false bottom therein, with a tubular portion ofsubstantiallyuniform cross-section and of length not greater than theinternal height of the dustbin and essentially with a further tubularportion preferably at the upper end of the bag which portion isdoubled-back or pleated or otherwise folded such that the upper edge ofthe bag will not normally project above the -dustbin' and will not beliable todamage, and'such that the 25, bag can be readily extendedupwards or length ened to permit the closure and the sealing of the bageven if the dustbin be substantially completely full of dust or refuse.

In a modified form of bag which is otherwise the same as that above setforth, the extensibility is provided by the further portion being slitdownwards in several places and reinforcing patches being provided atthe lower ends of the slits to prevent them extending, such slit portioneither being folded as above set forth or being left so that it can befolded outwardly downwards over the edge of the dustbin after insertionof the bag therein. In the latter case the fold may be protected fromdamage by means of a ring such as of metal which is adapted to be fittedupon the top of the dustbin.

The bag preferably consists of paper and/or fabric of one or morethicknesses impregnated so as to be waterproof or otherwise renderedsubstantially waterproof and preferably also impregnated withdisinfectant if the waterproofing material is. not a disinfectant. Noclaim is herein made per se to waterproofing the bag or to impregnatingit with a disinfectant.

The doubling back or pleating or folding of the upper portion of the bagto provide the extensibility may be of the accordian type but preferablycomprises a fold outwards and downewards followed by a fold upwards, ora fold outwardsand downwards, a longer fold upwards, a further fold:inwards and downwards and finally a fold upwards. Alternatively the bagmaybe formed with a single and relatively long fold inwards or outwards,and downwards.

The'bag may be made of flaring shape at the mouth to permit the doublingback or pleatingor folding aforesaid. Such flaring maybe produced forexample by forming one or more slits and gumming, stitching, orotherwise applying insertions. '7

The invention also comprises the combination with a manufactured bagasabove set forth of one or more fasteners secured in or near the upperend thereof whereby when the bag is extended it may be readily andquickly sealed by the dustman. Such a fastener may assume a variety offorms. In one form the fastener may be a spring or resilient clip orseveral spring clips secured to the edge of the bag, and adapted toclose the latter when extended and the upper end folded over; such clipmaybe, similar to the well known paper clip such as'that sometimes knownas a slider or the pronged type adapted to perforate thepaperand be bentover. The clip may be secured to the bag by means of a pivotv or rivet.Such clip or clips may be so formed or arranged that they serve forsupporting the bag within the dustbin such as by hooking over its edge,and also if desired for assisting in extending the upper end of the bagprior to closing it by means of said clips.

Alternatively the upper edge of the extensible portionof the bag may beeyeletted and. threaded with a string or wire or cord which may first bepulled for extending or lengthening the bag and then by further pullingused to bunch and close or seal the bag.

When av protecting ring is used as aforesaid it may have a relativelynarrow'flange portion adapted to fit upon the top edge, of the dust-10in, and a skirtv portion extending downwardly inside. or outside forinstance a distance corresponding to the extensible portion of the bag.Such protecting ring may be split. at. one place or otherwiseconstructed so that it can be read ily applied to the dustbin.

To enable the invention to be clearly understood and carried into effectit will be described with reference to the accompanying drawing in WhichFig. 1 is a sectional elevation of a. dustbin showing therein one formof a'bag in accordance with the invention.

Fig. 2 is. a sectional elevation of one; of the no edge of a bag havingsecured thereto another form of fastening and Fig. '7 is a sectionalelevation" of'a dustbinhaving a bag therein folded outwards over the Vedge of the dustbin and protected against damage. Y

Referring to Fig. 1 of the drawing, 1 is the main portion of the dustbinand 2 the lid, and 3*is thelo'ag or liner which may be formed ofmaterial such as. hereinbefore set forth and which isprovided at itsupper edge as indicated at 4- with a double fold arranged so thatnormally the upper edge of the bag does not pro-. ject at the upper edgeof'the dustbin, but permits the bag to be extended beyond the edge ofthe dustbin and closed upon the-contents of the bag in any convenient-manner, such for example as by the means hereinafter described.

It willbe understood that instead of there being a double fold, as shownat 4. in Fig. 1, there may be only a single fold, extending q upon theoutside of the bag such a distance as will permit the bag to be closedupon its contents after being extended. iThe extreme edge of the bag ispreferably permanently folded,

as indicatedat 5, and .gummed or stitched or stapled.

In the modification shown at Fig. 2,,the upper edge of the bag isrendered extensible by being folded first; outwards and downwards asindicated at 6, then upwards as-indicated at 7, next inwards anddownwards as indicated at 8, and then upwards as indicated at 9. Therefuse, bag as above described'may be manufactured by'forming from apaper and/or fabric band of appropriate width, a substantiallycylindrical tube or a tube of rectangular section, by securing 'theedges of said band with a substantially waterproof adhesive and/or withstitches or staples or other fastenin'gs of .wire or thread or the like,said tube towards its upper end being flared to permit of the provisionof theaforesaid pleating or folding essentially necessary to enable thebag to be sufficiently protected against damage by the insertion intothe bin of refuse and'the replacement of the lidof the bin,'whilstpermitting-the bag to be subsequently elongated sufiiciently. to beproperly olosedon its contents. Thus a'machine for mak ing such bags maybe of a generally known kind comprising in combination means for feedingfrom a roll of paper and/or fabric of appropriate width to anapproximately cylindrical or rectangular former or guide which" howeveris expanded .or. flared slightly at the delivery end for the-purposeabove mentioned, with known means for mechanically gumrning. theadjaCenaedges tof rm the tube, and means forgcutting oif'lengths of tubesufiicie'nt to pro vide for the formation .firstly of. the bottom of thebag and. secondlyof the pleating or.fo1ding of the upper end to permitthe extension thereof as aforesaid.

The closing of the bottom of the bag may be effected by forming slitsand/0r folds of appropriate length and shape at the one end of the paperand/or fabric and then applying gum, cement or other adhesive andfinally folding over against a mandrel so as to form the substantiallyfiatbottom to the bag, stitches of thread or wire or staples being usedif necessary.

The pleating or folding of the top of the bag Imay be effected by a handoperation such as by the. use of a suitable jig as permitted by theflaring of the end of the paper cylinder.

The necessary pleating or folding may be effected when the paper and/orfabric coming from the roll is still in the flat or plane state, namely,by means of appropriately mutually moving folding or pleating membersafter whichthe paper is preferably subjected to a pressing or creasingoperation such as between the feeding rollersor by other pressing means.

In the alternative method illustrated by Fig. 3

the flaring of the upperend-of thebag 3 may be effected by providing aplurality of longitudinal slits 10, for instance four slits and thenflaring the bag, as clearly shown, by applying insertions 11 by gumming,stitching or otherwise. The invention also includes a bag having slitssuch as 10 (Fig. 3) without the insertions 11, provided the ends of theslits are prevented as shown in Fig. 3 from extending by tearing bymeans of reinforcing patches 12 of paper, fabric, canvas, or otherconvenient material, which may be applied by gumming, stitching orstapling for example.

I propose creosote as a convenient material for both waterproofing anddisinfecting the paper but I do not limit myself to the use of creosotefor the purpose.

Referring next to Figs. 4 and 5 of the accompanying drawing, oneconvenient form of clip 13 for closing the bag upon its contents afterextension may comprise a wire 13 bent to the shape shown in Fig. 4,having downwardly extending clip portions 14 adapted to slide over thefolded'upper edge of the bag as indicated at 15 in Fig. 5. The wire hasextension 16 bent downwardly and terminating in an eye 1'7 which may besecured to the edge of the bag by means of an eyelet or rivet, so as topermit the wire clip 13 being turned upwards and then downwards again tosecure the folded edge of the bag, The clip 13 may be engaged upon theedge of the dustbin to support the bag thereon.

Instead of the slider type of clip shown in Figs. 4 and 5, a clip of thepronged paper fastener type may be used, adapted to perforate thematerial of the bag and then be bent or spread outwards. Sucharrangement is illustrated at Fig. 6, wherein the fastening clipcomprises a strip of metal with pointed ends and bent to the shapeclearly shown so as to have a head portion 18, retaining portions 19 andprong portions 20, the latter being bent as shown sideways untilrequired for fastening the bag, when they may be bent outwards at rightangles to the head 18, forcedthrough the opposite side ofthe bag andbent outwards oppositely to seal the bag.

Referring finally to Fig. 7, the upper end of the bag 3 may be formed aspreviously herein described, with simple longitudinal slits and thenwhen inserted in the dustbin Said edges may bebentxoutwards aroundtheupper edge of the bin, as shown at 21 in Fig. '7. The fold of the bagand the portion 21 thereof may be protected against damage by means of aprotecting ring 22 comprising a portion adapted to fit upon the top edgeof the dustbin and an external skirt portion 23 adapted to lie outsidethe dustbin. The ring 22 and outer portion 23 may be split as indicatedat 24 to permit the ring to be readily applied to the dustbin, the ringbeing advantageously made resilient. In some cases, if desired, the ring22 may be provided with an upstanding tongue (not shown) or theequivalent which may be used in a manner otherwise well known to permitthe dustbin lid being tilted about said tongue or the equivalent, whichacts as a fulcrum. In cases where the extensible portion of the bag isformed to be disposed within the bin, the skirt portion 23 of the ringmay be arranged to extend inside the bin toprotect said extensibleportion. Instead of the above described ring, a plurality of clips maybe used distributed around the rim of the bin.

It will be understood that various modifications may be made withoutdeparting from the scope of the invention. Thus for example the bag maybe constructed in the form of a tube and a separate bottom appliedthereto and gumined and/0r stitched or stapled in position. 01' thebottom of the bag may be made of usual form, then blocked to therequired shape on a mandrel or former, whilst gum or stitches or staplesmay be added if desired.

In order to prevent the bag being retained by suction in the bin, thelatter may be formed with a plurality of holes such as indicated at 25in Fig. 1, or alternatively, holes may be similarly provided in the bagitself.

An alternative way of closing the bag upon its contents may be byapplying staples by means of a hand-operated stapling device which maybe carried by the dustman.
